serial No. 238,235. 1

To aZZfwwm it may concern Be it known that I, CLARENCE D. BAIRD, a citizen of the United States, residing at Alexandria, in the county of Dekalb and State of Tennessee, have invented certain new and useful Improvements in Gas-Holders, of which the following is a specification.

This invention relates to acetylene gasgenerating apparatus and more particularly to an in'lprovement in the gas collecting and storage devices, this application being furthermore a division of lny copending application filed June 30, 1917, Serial No. 177 ,9:20.

The object of the invention is to provide anovel construction of collecting and storage chamber for the generated gas which will provide for the collection of the gas without likelihood of leakage and will serve also as a means for cooling the gas before its delivery to the supply pipe.

A further object of the invention is to provide avery compact relative arrangement of the generating and storage chambers of the apparatus.

A further object of the invention is to provide means for carrying 0E to av safe point, any excess gas which may be generated.

In the accompanying drawings:

Figure 1 is a vertical sectional view through one form of the apparatus embodying the present invention;

Fig. 2 is a similar view illustrating another form of the invention;

Fig. 3 is a detail vertical sectional view illustrating the means provided for conducting the gas from the generating chamber into the collecting and storage chamber.

In the drawings the numeral 1 indicates the generating chamber of the apparatus at the top of which is mounted the usual carbid hopper indicated by the numeral 2 and from which the flow of carbid is controlled through the movement of a valve 3 normally closing the outlet in the lower end of the said hopper. The numeral 4 indicates the usual gas bell into which the generated gas is discharged before being carried off to the burners, and means is provided for autolnatically controlling the opening and closing movements of the valve 3 upon raising and lowering of the gas bell lso that when the bell lowers as the gas is consumed, the

valve will be automatically opened to provide for the supply of a fresh charge of carbid to the water in the generating chamber.k However, as all of the 'previously referred to structure constitutes the subjectmatter of another application it need not be further described. v

p The gas bell l is surrounded by the collecting and storage chamber embodying the invention and in the forms of theV invention shown in thedrawings, the generating and collecting chambers are located close together and in fact are united, being divided from each other,however, interiorly by a parti tion wall indicated by the numeral 5. The numeral 6 indicates a cut-off valve the casing offwhich is located within the generator land has an inlet branch 7 through which the generated gas may enter the said casing. The valve casing also'has an outlet branchV indicated by the numeral 8 which` leads through the partitionwall and into the annular ystorage chamber heretofore referred to. The said storage cllalnber is indicated ill eneral by the numeral 9 and the same is formed between spaced cylindrical walls 10 and 11, anda connecting top wall 12. The wall 10 is supported at its lower end by a bottom 13 which in turn is supported by suitable brackets let upon the closed bottom 15 of the said chamber. Thus the walls 10 and 11 define an annular space closed by the top wall 12 and comlnunicating with the space between the bottom members 13 and 15. It will also be understood at this point that the wall 10 and bottom portion 13 form a compartment in which a quantity of water is poured and inwhich the gas bell 4 is housed.

Gas entering the collecting chamber 9 through the valve casing 6, will pass up through a pipe 16 which extends upwardly from the bottom 13 of the gas bell compartment, the pipe being open at its upper end, and at its lower end being in communication with the space between thebottom members 13 and 15. The upper end of the pipe 16 is, of course, in commimication with the interior of the gas bell 4, andthe said 'end of the pipe is located a suitable distance above the maximum water level within the gas bell compartment. From the bell 4, the gas passes downwardly through a pipe 17 which also opens at its upper end into the gas bell above the water level, and this pipe leadsthrough the Vbottom 13 of the gas bell compartment and thence laterally' between the bottom members 13 and 15, as indicated by the numeral 18, and thence upwardly as at 19 within the collecting chamn ber 9 and finally out through the wall 11 of the saidpchamber and to the burners.

In thatl form of the rinvention shown in Fig. 2 of the drawings, the gas bell l is provided interiorly with a tubular gas arm 20 which is closed at its upper end and which extends downwardly within the said bell and .is open atA its lower end, but has its lower endllocated above the lower end of the bell. Extend-ing downwardly intol the gas bell compartment is an escape pipe 21 which has a branch 22 leading directly upwardly and into the gas arm 20, the upper end of thisy branch being open and communicating with the interior ofthe said arm. It will now be understood that should gas be too rapidly generated or should `the feeding means become disarranged and sufficient gas generated to move the bell upwardly until the lower endof the gasarm is located above the water level, the excess gas generated will pass through the branch22 of the pipe 21 and may be led by the said pipe to any point where it maybe safely discharged.

Having thus described `the invention,

` what is claimed kas new is:

1, In a gas generator of the class described, a generating chamber, anda gas collecting device including spaced :inner and outer walls providing an annular chamber closed at its top, means for conveying gas from the generating .chamber to the collecting chamber, a gas bell arranged within the compartment defined by the inner wall of the collecting means, a gas conducting pipe leading from the bottom of the collecting chamber upwardly into the gas bell, anda gas conducting pipe leading from the interior of the gas bell downwardly and into the bottom of the collecting chamber and thence upwardly within the said chamber and through the outer wall thereof for supply service.

2. In a gas generator of the class described, a generating chamber, means for collecting gas generated within the chamber including spaced inner and outer walls and spaced bottom walls forming a collecting chamber to receive the generated gas, a gas bell within the compartment defined by the inner wall and the upper one of the bottom walls, a pipe leading upwardly from the said inner bottom wall and having an Open upper end communicating with the interior of the gas bell, and a conducting pipe also leading into ythe gas bell and communicating with the interior thereof and extending through the upper bottom wall and between the said walls and upwardly between the inner and outer walls and thence through the said outer wall.

In testimony whereof I aliix my signature.
